Tests witnessed by

» The European Commission Project

Officer

» RTE, RED Electrica and Tennet

representatives

» A representative of an independent

mandated test laboratory.

In less than 5.5 milliseconds, the HVDC circuit breaker reaches total interruption of currents

exceeding 5,200 amps with switching voltage peaking at more than 160 kV

Tests to date all successful

» Dielectric lightning withstand

» Short time current withstand up to 10kA

» Temperature rise test under rated or

overload currents

Successfully tested in conditions of real actual operational constraints for

a high-voltage DC transmission grid

TECHNOLOGY EVOLUTION

The developments of joint balancing grids


Conclusion

» The mix of conventional energy resources with high amounts of decentralized

renewable energy sources reduce network stability

» Stably balanced grids are basis for constant energy availability

» The extension from national over regional towards international

interconnections is a vital mean to increase the balance between

generation and load

» HV transmission networks play a mayor role in wide area interconnection

» Smart HV technologies, such as HVDC, FACTS, WAMS and state-of-the-art

Network Management Systems are fundamental assets of balanced

European grids …

… and are available
